Wettability enhancement of polystyrene with electron cyclotron resonance plasma with argon

摘要: Polystyrene cell-culture substrates were treated with argon glow discharge to make their surfaces hydrophilic. The process was novel in that it used a microwave electron cyclotron resonance (ECR) source for polymer surface modification. processed at different powers and time periods, the modification assessed by measurement of water contact angle. A decrease angle observed increasing power processing time. Beyond certain limit duration exposure, however, deterioration occurred. optimum conditions making hydrophilic without samples identified. plasma parameters Langmuir probe measurement. Fourier transform infrared spectroscopy attenuated total reflectance showed evidence induction hydrophilicity on surface. micromorphology examined scanning microscopy. results prove ECR an efficient method enhancing wettability surfaces.
